Exhibit 99.2

                 Vicor Announces V-I Chip License to Celestica

    ANDOVER, Mass.--(BUSINESS WIRE)--Oct. 20, 2003--Vicor Corporation
(NASDAQ: VICR) today announced that it has entered into a
non-exclusive license with Celestica Inc. to manufacture and sell the
V-I Chip(TM) (VIC) Product Family. V-I Chips are the building blocks
of the new Factorized Power Architecture (FPA) that Vicor announced
this past April.
    V-I Chips deliver up to 240 Watts of power in a surface-mount
(SMD) ball-grid array (BGA) package occupying less than 0.25
cubic-inch of space, with power densities up to 960
Watts-per-cubic-inch -- five times better than competitive products.
Available in both an "in-board" BGA configuration and an "on-board"
leaded SMD configuration, and capable of efficiently delivering
currents greater than 100A to the point-of-load, V-I Chips set new
standards for conversion efficiency, fast response to dynamic loads
and low noise performance.
    According to Andrew Hilbert, Senior Director of Marketing for
Vicor: "When compared to the bricks of distributed power or the
non-isolated point-of-load converters powered by an intermediate bus,
V-I Chips and FPA represent a revolutionary and disruptive power
system solution that offers step-function improvements in performance
at a low cost. Now, with Celestica as a licensee, OEMs will be able to
source these products from two recognized leaders in the power
conversion industry."
    "We are pleased that Celestica has become a licensee for V-I
Chips," says Patrizio Vinciarelli, President and CEO of Vicor.
"Celestica's reputation as a first-tier supplier of high-quality power
conversion products, and its leadership in innovative electronics
manufacturing services, qualifies it to become an excellent alternate
source. We believe that this license will amplify the market
opportunity and accelerate the market penetration of V-I Chips and
Factorized Power."
    V-I Chips are currently available from Vicor and will soon be
offered by Celestica. Datasheets are available at www.vicorpower.com.
